{"title":"Base Layers","description":"\u003cp\u003eMerino wool is non-negotiable for base layers. Unlike synthetics, it regulates temperature through actual temperature shifts, naturally resists odor, and performs when wet—critical on long trails. Our 2-pack crew socks are 80% merino, engineered with reinforced heel and toe for durability and built on a contoured last for fit without bulk. Layer these under anything from canyon scrambles to alpine bivouacs. The insulated vests pair merino with precision quilting to trap warmth without added weight. Technical layering means fewer clothes. Fewer clothes means lighter pack.\u003c\/p\u003e Shop our \u003ca href=\"\/products\/merino-socks-crew\"\u003eMerino Wool Hiking Socks\u003c\/a\u003e.","products":[{"product_id":"merino-socks-crew","title":"Merino Wool Hiking Socks — Crew (2-pack)","description":"\u003cp\u003eMerino wool is still the best material for hiking socks.
